Photo websites offline after possible breach

The online photo websites of Rite Aid, CVS, Costco and Wal-Mart Canada remain offline in the wake of a possible data breach at the company that hosts all four sites. The companies say their photo sites remain shut down as a precaution. All four sites are administered by Canada-based PNI Digital Media, which is owned by Staples Inc. Late last week, Staples acknowledged that PNI was investigating a potential credit card data security issue but wouldn't say how many companies or people could be affected. All four companies say that their other websites aren't affected by the possible hacking.

Sikorsky to be acquired by Lockheed for $9B

Lockheed Martin said it would buy Sikorsky Aircraft, the maker of the Black Hawk helicopters favored by the U.S. military, from United Technologies Corp. for $9 billion in cash.

The transaction would be structured in a way that generates a tax benefit of about $1.9 billion for Lockheed Martin and its shareholders.

Payment processor First Data files for IPO

U.S. payment processor First Data Corp. filed with U.S. regulators for an initial public offering of common stock. The company said it would continue to be controlled by buyout giant KKR & Co. after the IPO. First Data did not specify the underwriters of the offering. KKR took First Data private for about $29 billion in 2007. As one of the mega-leveraged buyouts that came to epitomize the credit binge preceding the 2008 financial crisis, First Data has proved to be a challenging investment for KKR.
